Can you tell us more about what really happens to disk drives when the
power is cut while a block is being written? We engage in a lot of
uninformed speculation, and it would be nice if someone who really knows
told us....

Do drives have enough capacitance under normal conditions to finish
writing the block? Does ECC on the drive detect that the block was bad
and so we don't need to detect it in the FS?
